Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed June 15,1905. Serial No. 265,347.

To (all 2071/0710 it may concern:

Be it known that I, GEORGE E. HULsE, residing at East Orange, in thecounty of Essex and State of New Jersey, have invented certain new anduseful Improvements in GasLamps, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to gas-lamps and the like, and is especiallyadapted for use in connection with car-lighting systems, althoughcapable of use as to several of its features in a variety of relations.

One of the objects thereof is to provide a device characterized byincreased simplicity, efficiency, and convenience.

Another object is to provide in a lamp structure of the above type aneflicient and firm support for a plurality of independent lamps.

Another object is to provide means where- 'by the several lamps embodiedin the lamp structure may be easy and convenient of access for purposesof cleaning or repair and at the same time one in which the jar or shockusually incident to such operations may be reduced to a minimum.

Another object is to so construct the lamp structure that the severalassembled parts will not vibrate or rattle.

Another object is to provide means adapt-- ed to be convenientlyoperated to regulate the quantity of air admitted to the mixingchambersof the several lamps comprising the lamp structure.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts, which will beexemplified in the embodiment hereinafter described and the scope of theapplication of which. will be indicated in the following claims.

Referring now to the drawings, wherein is illustrated one of the variouspossible embodiments of my invention, Figure 1 is an elevation, partlydiagrammatic, of the same. Fig. 2 is a horizontal sectional viewthrough. the lamp structure, some of the parts being broken away. Fig. 3is a vertical sectional view on the line a: m of Fig. 2. Fig 4 is asectional view of a detail.

eral parts ready of access Similar reference characters refer to similarparts throughout the several views of the v drawings.

As tending to render clearer certam of the various features of mylnventlon, it may here be noted that in lamp structures of this typewherein a plurality of independent lamps are employed it is essentialthat a firm and stable means he provided to hold the several lamps inposition. It frequently becomes necessary to clean and repair the lampsor replace the mantles or other parts, and as such work is usuallyperformed by a porter or other person equally unskilled means should beprovided to allow a ready access to the several parts. detaching ahinged globe or bowl inclosing the lamp or lamps, but often thereplacing .of the globe or bowl to its normal position has beenaccompanied by disastrous results This is usually accomplished by eitherto the globe itself or to the fragile mantle on account of the incidentjar or shock resulting therefrom.

e means employed to regulate the quantity of air admitted to themixing-chamber of the lamp also requires time to time, and it thereforeis essential that such means be rendered easv of adjustment, but at thesame time so constructedas to be free from liability of working loose. I

regulating from have therefore found it desirable to provide a frame orspider adapted to support the several lamps in a firm position andimmovable relation, and while rendering the sev- I have provided acushioning means interposed between the 0 supporting member and or bowladapted when swung into position to shock which might be the swingingglobe the same is being prevent all jar or occasioned thereby from beingcommunicated to the parts from 5 which the delicate mantles aresuspended. The cushioning means also operates to reduce to a minimum thedisagreeable rattling of the detachable parts I have also providedregulating devices for-the air-inlet ap- TOO ertures of the severallamps capable of convenient operations and at the same time not liableto work loose.

Referring now to the drawings, the lamp A is suspended from the deck Bof railway- IO 5 car or similar structure by a plurality of hollowsuspension-arms 1, suitably secured to said deck B, as by plates 2, andare attached at their lower ends in the present instance to a preferablyannular supporting member or ring 3. While this supporting member 3 isherein shown annular in form and is designated a ring, I wish it to beunderstood that the term is used only in a descriptive sense and that Iintend to embrace by this term any structure of this nature whetherannular or of a different shape.

Suitably secured. to ring 3, as by screws 4, are a series ofinwardly-extending substantially T-shaped members 5, to each pair ofadjacent arms of which is secured one of a series of lamps 6 by suitablemeans, as screws 7, as clearly shown in Fig. 2 of the drawings. Thelamps therefore form connecting means between the adjacent arms ofmembers 5, forming a continuous structure, the whole comprising whatmight be termed a composite spider.

As all of lamps 6 are of similar construction, a description of one lampwill suflice.

As clearly shown in Fig. 3 of the drawings, the body 7 of the lamp hasarranged therein a mixing-chamber 8, leading into gas-nozzle 9, uponthe. exterior of which is secured a supporting-spool 10, of a hardrefractory material, and tied to spool 10 is a pendent mantle 11.Lamp-body 7 is provided with a series of openings 12, (shown in dottedlines of Fig. 3 of the drawings,) which are adapted to conduct productsof combustion from the lamp, and is surmounted by a deflector 13. Atranslucent globe 14 is detachably secured to lamp-body 7 by a suitablecatch 15. The

last above described features relating to lamp 6 form, however, no partof my present invention and are mentioned solely for the purpose ofrendering my invention clearer of understanding. Lamp-body 7 is providedwith an inlet-aperture 16, into which is tapped an externally-threadedbushing 17 designed to be seated firmly therein and held to frictionallyresist rotation. Into an enlarged and internally-threaded end of bushing17 inlet-nipple 18 is loosely tapped, which nipple is provided with areduced split end, the sections 19 of which are adapted to springoutwardly and frictionally engage the interior walls of bushing 17. Thenipple 18 is provided with a milled edge 19 and is capable oflongitudinal adjustment in bushing 17, the purpose of which will beapparent hereinafter, the split ends operating to maintain the same inadjusted position. Hollow suspension-arms 1, provided withregulating-cocks 20, are adapted to convey a supply of gas to each oflamps 6, the gas passing through apertures 21 in supporting-ring3, andinto each of said apertures is tapped an inspirator-nipple 22, eacharranged in proximity and in registry with one of air-inlet nipples 18,as clearly shown in Figs. 2 and 3 of the drawings. Exit and inletnipples 22 and 18, respectively, comprise an inspirator,

the purpose of which is to carry into the mixing-chamber with theingoing gas a suitable quantity of air to form a burning mixture, and.inlet-nipple 18 is adjustable toward or from exit-nipple 22, as aboveexplained, in order that the quantity of air taken in may be regulatedor determined. I

Supporting-ring 3 carries one member 23 of a hinge 241, to which isattached bezel-ring 25, normally held in a detachable position againstsupporting-ring 3 by latch 26, controlled by spring 27, suitably securedto supportingring 3. interposed between bezelring 25 and supporting-ring3 and located in depressions 28 in supporting-ring 3 are a series ofpins 29, held in an extended position by springs 30 located therein andprevented from being detached by staples 29, said springcontrolled pinsbeing adapted to engage with the upper surface of bezel-ring 25. Asubstantially U-shaped preferably annular supporting-ring 13 engagesbezel-ring 25 and extends under an inturned edge or lip 32 of atranslucent globe or bowl 33, inclosing lamps 6, which globe or bowl issupported from within by ring 31 and has interposed there between astrip 34 of asbestos or other soft highly refractory substance, saidstrip extending about the inturned edge or lip to also separate the samefrom bezel-ring 25. Arranged above lamp A and extending through deck Bis a chimney C, designed to conduct the products of combustion therefromto the exterior of the structure.

Although from the above description the operation of my invention shouldbelargely obvious, it will be understood that the releasing of latch 26from bezel-ring 25 will allow the translucent globe or bowl 33 to beswung downwardly, thus exposing the several lamps and permitting repairto be made or portions replaced or adjusted. When globe 33 is returnedto its original position, the cushioning means interposed between thesupportingring 3 and bezel-ring 25 will operate to take up any jar orshock incident thereto. While in this embodiment I have preferably shownspring-controlled pins 29 in the above rela tion, it is obvious that anyother cushioning means may be employed in said relation withoutinvolving a departure from the spirit of my invention.

It will thus be seen that I have devised a lamp structure characterizedby simplicity, efficiency, and convenience and one in which a firm andstable support is provided for the lamps, the several parts beingrendered easy of access, and vibration and rattling is prevented, thecushioning means operating to prevent injury to the delicate mantlesduring the several operations above described.

Although my invention is herein shown be mixed therewith to anddescribed as applied to lamps of the in candescent mantle type, I wishit to be understood that I do not intend to limit its employment tolamps of such type, as many of the features are adapted for use in avariety of relations in other structures.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention could be madewithout departing from the scope thereof, I intend that all mattercontained in the above description or shown inthe accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
